Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overlap type shell particularly used for sports shoes such as ski boots, ice skates or roller skates.

[0002]

BACKGROUND OF THE INVENTION It is now known to manufacture shells having two flaps that overlap each other such that they can be secured by conventional means such as levers. One of the problems with the prior art is that the shell
The rigidity is such that it is difficult for the user to insert the foot. This is because the shell is made of synthetic resin and the flaps must be separated from each other.

Problems also arise when using soft synthetic resins. This is because the shell rigidity is required to properly transmit the motion applied by the user. It is also highly desirable to limit the ingress of water inside the shell in the flap overlap region during sports exercise. Also, in use, the flaps actually tend to slide relative to each other, which results in the formation of small openings, especially along the flap edges. If the flap is not very rigid, such an opening may be very large. However, a very high flap stiffness runs counter to the desire to facilitate easy foot insertion.

[0004] Italian utility model registration No. 162434 discloses a shoe, especially for skiing. This shoe is
It comprises a shell or tongue extending upwards from the front towards the instep region and a collar-like intermediate element surrounding the intermediate region of the sole of the shell. There is a longitudinal opening in the tongue of the shell and there is a cuff portion articulated to the intermediate element or shell.

Even this solution has drawbacks. This solution, in the first place, seeks to eliminate the problems associated with the water resistance of the shell, but is not of the overlapping type and still requires the production of additional parts to be preassembled in the shell. is there. Moreover, a longitudinal opening is still formed in the intermediate element, which opening is connected to the multiple transverse notches. These notches increase the risk of water ingress and in any case considerably weaken the structure.

In order to facilitate the insertion of the foot sufficiently, it is still necessary in any case to configure the longitudinal opening provided in the intermediate element to open and act on the fixing device,
It is also necessary in any case to force the end of the intermediate element to deform by pushing the tongue forward to form the longitudinal opening. This ultimately results in difficult leg insertion, complicated boot construction, and nevertheless water ingress.

SUMMARY OF THE INVENTION The present invention, therefore, provides a shell which allows optimum insertion of the user's foot and which has an optimum tightness against water ingress with overlapping flaps. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above technical problems and solve the above-mentioned drawbacks of the prior art.

Within the scope of the above objective, an important objective is to provide such a shell which maintains the structural rigidity required for optimum ski control. Another important object is to provide a shell that is simple in structure and easy to industrialize. Another important objective is to provide a shell that is reliable and safe to use.

Another object is that the manufacturing cost is low, and
It is to provide a shell that can be manufactured using conventional equipment or devices.

[0010]

The above and other objects which will become apparent from the following description are achieved by an overlapping shell which is particularly used in sports shoes such as ski boots, ice skates or roller skates. The shell comprises at least one recess in the at least outer flap connecting two separate regions of the periphery of the outer flap, the at least one recess being along a direction that acts on the lateral metatarsal bone of the foot. It is characterized by being formed.

The features and advantages of the invention will be apparent from the detailed description of specific embodiments, which are shown by way of non-limiting example in the accompanying drawings.

[0012]

The shell having a recess at least on the outer flap has a simple structure. Moreover, since the shell is of an overlap type, it has a high degree of tightness against water intrusion. or,
The outer flap is provided with a recess so that the user
The outer flap can be easily opened, which is convenient for foot insertion. Moreover, since the shell can be made of a rigid synthetic resin, the movement of the motion from the foot to the sports equipment is optimally performed.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the accompanying drawings, reference numeral 1 designates a semi-rigid, overlapping shell for particular use in shoes such as ski boots, ice skates or roller skates. The shell 1 comprises an inner flap 2 and an outer flap 3, the outer flap overlying the inner flap and being formed in a substantially central front region of the shell 1.

At least one recess 4 is formed in the outer flap 3, for example during molding. The recess is provided on the inner side surface 5 or the outer side surface 6 of the outer flap 3. The at least one recess 4 connects two separate regions of the outer flap's perimeter, such as the upper edge 7 and the longitudinal perimeter 8 of the outer flap 3.

The at least one recess begins at the upper peripheral edge 7 and is oriented so as to act on the lateral metatarsal region of the foot, as shown in the accompanying drawings. This recess 4 is
It is preferably connectable to a notch 9 near the upper peripheral edge 7, the notch 9 being formed longitudinally with respect to the outer flap 3. The shell thus obtained can be constructed of a synthetic resin with sufficient rigidity to optimally transmit motion from the foot to sports equipment such as skis or wheels of skates or blades of ice skates. And this shell allows optimal foot insertion.

By gripping the outer flap 3, the user can easily open the shell, as shown in FIG.
Optimal insertion of the foot can be achieved. Notch 9, especially recess 4
Is present, so it is convenient to open the shell. This recess 4 allows the flap 3 to be folded outwards, resulting in the insertion and removal of the foot.

As described above, it is obvious that the present invention achieves the intended purpose, and the insertion of the user's foot can be optimized, and the tightness of the overlapping flaps against water intrusion can be optimized. It was revealed that a shell that can be used for things is provided. Moreover, the shell is very easy to obtain and easy to industrialize.

The present invention can be variously modified, and all modifications are within the same inventive concept. The materials and dimensions that make up the individual parts of the device can be optimized according to particular requirements.

[0019]

As described above, in an overlapping shell for sports shoes such as ski boots, ice skates or roller skates, the shell of the present invention connects at least two separate regions of the outer flap periphery. One recess is provided in at least the outer flap, and the at least one recess is formed along a direction that acts on the lateral metatarsal region of the foot, so that the user's foot can be optimally inserted and Optimum tightness against water ingress with overlapping flaps. Further, the structural rigidity of the shell required for optimum ski control can be maintained. Further, the shell of the present invention has a simple structure, is easy to be industrialized, has a low manufacturing cost, and can be manufactured using a conventional apparatus, and is highly reliable and safe in use.
